Can dogs eat grapes or raisins?
Toxic — never feed
No. Grapes and raisins can cause sudden kidney injury in dogs, and there is no established safe amount — some dogs react badly to a very small quantity while others seem unaffected, and there's no way to know in advance which yours is. In India the bigger risk is kishmish hidden in sweets, kheer, halwa and dry-fruit boxes, especially during festivals.
Why
The mechanism isn't fully settled in veterinary science, but the association with acute kidney injury is well established, and raisins appear to carry more risk than fresh grapes because they're concentrated. Because susceptibility varies so much between individual dogs, vets treat any grape or raisin ingestion as worth acting on rather than calculating a threshold.
What to watch for
Vomiting is often the earliest sign, sometimes within hours, followed by tiredness, loss of appetite, and later reduced urination. If your dog has eaten grapes, raisins or a sweet containing kishmish, call your vet or the nearest 24/7 emergency hospital straight away. Don't wait for symptoms and don't try any home remedy. Tell them roughly how much was eaten and when.
Frequently asked questions
My dog ate one raisin — is that dangerous?
It may well be fine, but because sensitivity varies so much between dogs there's no reliable safe amount. Call your vet and describe what and how much.
Are raisins in kheer or halwa a problem?
Yes — kishmish in Indian sweets is one of the most common ways dogs are exposed here. Keep festival sweets well out of reach.
What about grape juice or grape-flavoured things?
Avoid actual grape products. Artificial grape flavouring isn't the same thing, but there's no reason to offer either.
